avin w. rim, or BRo onL n, new oRK METHOD FOR Levine can moons nn, AISLE srmrs.

Application filed December 31, 1927. Serial No. 243,889.

This invention relates to av method for lay ing car floors and it consists in the novel steps and procedure hereinafter described and claimed.

In carrying out the improved method a flooring composition of plasti material which contains ingredients that work' togethe r when mixed with a liquid binder causing a chemical settingup action is used as a foundation. This foundation layer possesses sufficient flexibility as to effectually withstand the strains to which it is subjected in passenger car service.

A prime object of the present invent-ion is to provide an economical and efficacious method for inserting blocks of tile in the said foundation layer to add to the appearance of the floor surface without subtracting from the resiliency or strength of the floor.

The tile is furnished in sheets with paper glued upon the polished surfaces of the blocks and these tile are out from the sheet in the form of a group leaving the paper attached to the tile. The tile are tamped into the foundation layer .with the paper side up. In order to assistin maintaininga regular and uniform positioning of the tile, a perforated template of sheet steel, beaver board, or any other stiff material that will not buckle is provided. The perforations in the template correspond with the design in which the blocks are arranged. The template is laid upon the foundation layer just before it hardens and the tile inserted through the perforations in the template and tamped flush with the surface of the foundation layer.

The tile is tamped into the foundation layer of plastic material just as the said material is beginning to harden that the material which comes in contact with the faces of the tile blocks is additionally compressed or con'ipacted and thereby made strong and firm at'the walls'of the mortises so formed in the material and which hold the tile blocks.

hen the blocks have become set in the foundation layer, the template is removed and the upper surface of the foundation is gone over with a mason s flat trowel to smooth down any unevenness which might occur. The strips of paper which are permitted to remain adhering to the upper surfaces of the tile-blocks will become discolored by the material removed by the trowel from the bodyof the plastic material during the smoothing operation. At the same time, the

said strips protect the upper polished surfaces of the blocks and prevent the trowel and the discoloring material from coming in Contact with thesaid polished surfaces Of the blocks.

After the plastic material of the floor hardens a cloth which has been dampened with water is wiped around the tile blocks. This wiping action softens and removes the paper strips from the tile blocks leaving them clean and unmarr ed. 1

In the accompanying drawing I Figure l is a fragmentary horizontal sectional view of the end portion of a sleeping car showing lavatory floors and an aisle strip laid in pursuance of the new method i F gure 2 is a. plan view of a template used in carrying out the method;

As illustrated in Figure 1 of the drawing a sleep ng car 1 shown as being provided with an aisle strip 2 and lavatbrics 3 having floors 4;, the said aisle strip and floors having been laid in accord with the method described hereinafter.

In carrying outthe method, a foundation layer 5 of plastic material is spread upon the floor of the car in soft condition. TA template 6 having perforations 7 is laid upon the upper surface of the foundation layer 5. A sheet of paper 8 having tile blocks 9 glued thereon is used for holding the said tile blocks in flat condition. Several of the tile blocks 9 with the paper 8 adhering to their upper or polished surfaces are cut from the said sheet and these tile blocks are inserted in the perforations 7 of the template 6. The blocks 9 are inserted in the said perforations just as the foundation layer vijjbeginst o hardn- A nipping too s -iip' d t' h strips of paper .8 at the upper surfaces of the I blocks 9 which have been inserted in the ora i s of he m a e-and nr ss re' fi ownw rd lilieetiee s ied to li Sai tamping tool whereby the bTocks 9 ar'rorcd down into the material of the foundation layer 5, and with the upper surfaces of-the blocks flush with the upper surface of the said foundation layer. As the blocks are thus forced into the foundation layer they form recesses or pockets therein and coinpact or compress the material of the foundation layer about the walls of the said pockets so that the structure is solidified and strengthened around the blocks.

The tamping tool 10 is provided with a shoulder 11 spaced from the tile block on gaging end of the tool a distance equal to the transverse thickness of the template so that when the said tool is used for embedding the blocks in the foundation layer the shoulder of the tool impinges the template and thus the upper surfaces of the blocks will be flush with the upper surface of the foundation layer.

After all of the tiles have been tamped into place, the template 6 is removed from the floor surface. A mason using a flat trowel (not shown) then goes'over the upper surface of the foundation layer and smooths the said surface. In doing so some of the material of the foundation layer is scraped or moved upon the upper surfaces of the paper strips 8, thereby discolor-ing the said strips. Inasmuch as the strips are applied to the upper polished surfaces of the tile blocks they protect the said blocks and prevent the same from being scratched by the trowel or discolored by the material which is removed from the foundation layer during the said smoothing operation.

When the foundation layer has hardened and when the blocks 9 have become securely embedded therein, a damp cloth (not shown) is wiped over the strips 8 whereby the said strips are softened and are removed from the upper polished surfaces of the tile blocks, leaving the same polished and clean and positioned in the foundation layer in accordance with the arrangement of the perforations in the template. Thus a smooth floor or aisle strip is provided and the same is ornamented by the blocks which are different in color from that of the foundation strip and the presence of the blocks do not substract from the strength of the floor or aisle strip and at the same time materially add to the ornamentation and attractive appearance thereof.

Having described the invention what is claimed is 1. The method of laying a floor consisting in spreading a layer of plastic material in soft condition to form a foundation, placing upon said foundation layer a perforated template, inserting in the perforations blocks of dimensions corresponding with the dimensions of the perforations of the template, applying pressure to the blocks to embed them in the material of the foundation layer to a predetermined depth, and finally removing the template.

2. The method-of layinga floor consisting in spreading a layer of plastic material in soft condition to form a foundation, placing upon said foundation layer a perforated template, inserting in the perforations blocks of dimensions corresponding with the dimensions of the perforations of the template, applying pressure to the blocks to embed them in the material of the foundation layer to a predetermined depth with the upper surfaces of the blocks flush with the upper surface of the foundation layer, and finally removing the template.

3. The method of laying a floor consisting in spreading a layer of plastic material in soft condition to form a foundation, alacing upon said foundation layer a perforated template, inserting in the perforations blocks of dimensions corresponding with the dimensions of the perforations of the template, said blocks having a protecting sheet applied to certain of their surfaces, applying pressure to the blocks to embed them in the material ofthe' foundation layer to a predetermined depth, removing the template, and finally removing the protecting sheet from the blocks.

4. The method of laying a floor consisting in spreading a layer of plastic material in soft condition to form a foundation, placing upon said foundation layer a perforated template, inserting in the perforations blocks of dimensions corresponding with the dimensions of the perforations of the template, said blocks having a protecting sheet applied to their upper surfaces, applying pressure to the blocks to embed them in the material of the foundation layer to a predetermined depth, removing the template, and finally removing the protecting sheet from the blocks by washing.

5. The method of laying a floor consisting in spreading a layer of plastic material in soft condition to form a foundation, placing upon said foundation layer a perforated template, inserting in the perforations blocks of dimensions corresponding with the dimensions of the perforations of the template, said blocks having a protecting strip applied to certain of their surfaces, applying pressure to 'the blocks to embed them in the material of the foundation layer to a predetermined depth, removing the template, smoothing the upper surface of the foundation'layer, and finally removing the protecting strip from the blocks.

In testimony whereof I affix my signature.
